[Pacemaker] Resources move on Pacemaker + Corosync cluster with set stickiness

[Danilo Malcangio]

Hi everyone,
I've created an active/passive 2 node cluster following the 
documentation on clusterlabs.
My cluster has the following characteristics
Debian Wheezy 7.2.0
Pacemaker 1.1.7
Corosync 1.4.2

I've made it with the following configuration

node BX-1
node BX-2
primitive cluster-apache2 ocf:heartbeat:apache \
     params configfile="/etc/apache2/apache2.conf" 
httpd="/usr/sbin/apache2" port="80" \
     op monitor interval="10s" timeout="60s" \
     op start interval="0" timeout="40s" \
     op stop interval="0" timeout="60s"
primitive cluster-asterisk lsb:asterisk \
     op monitor interval="30" \
     op start interval="0" timeout="120s" \
     op stop interval="0" timeout="120s"
primitive cluster-ip ocf:heartbeat:IPaddr2 \
     params ip="10.2.30.10" cidr_netmask="20" \
     op monitor interval="10s" timeout="20s" \
     op start interval="0" timeout="20s" \
     op stop interval="0" timeout="20s"
primitive cluster-ntp lsb:ntp \
     op monitor interval="30" \
     op start interval="0" timeout="120s" \
     op stop interval="0" timeout="120s"
primitive cluster-tftp lsb:tftpd-hpa \
     op monitor interval="30" \
     op start interval="0" timeout="120s" \
     op stop interval="0" timeout="120s"
group cluster-group cluster-ip cluster-asterisk cluster-apache2 
cluster-tftp cluster-ntp \
     meta resource-stickiness="101"
location prefer-et-ipbx-1 cluster-group 100: BX-1
colocation cluster-dependency inf: cluster-ip cluster-asterisk 
cluster-apache2 cluster-tftp cluster-ntp
property $id="cib-bootstrap-options" \
     dc-version="1.1.7-ee0730e13d124c3d58f00016c3376a1de5323cff" \
     cluster-infrastructure="openais" \
     expected-quorum-votes="2" \
     stonith-enabled="false" \
     no-quorum-policy="ignore" \
     default-resource-stickiness="1"
rsc_defaults $id="rsc-options" \
     failure-timeout="60s"

I've set location constraint to have BX-1 as the preferred node at 
cluster startup, and group stickiness at 101 to avoid moving resources 
when the master node comes back up (following this guide 
http://foaa.de/old-blog/2010/10/intro-to-pacemaker-part-2-advanced-topics/trackback/index.html).

I've got the following problem: resources move when I reboot nodes.

If i stop corosync on BX-1 resources move to BX-2 and when i restart 
corosync on BX-1 they stay on BX-2 (as I expected).
But all this doesn't happen with reboot (when I reboot BX-1).
After the reboot of BX-1 resources move to BX-2 and when BX-1 comes back 
up the resources move back to BX-1.

What am I missing in the configuration??

Thank you very much for the support



P.s. I attach also the allocation scores obtained with ptest -sL

BX-1 has resources
